Cannot uninstall Microsoft Asp.Net 5 RC1 Update 1 msi

Every time I tried to build and run an Asp.Net Core RC2 web app project from Visual Studio 2015 Update 2, Visual Studio would lock up and crash.

Turns out that ASP.NET Core RC2 Preview 1 conflicts with ASP.NET 5 RC1 Update 1, so I needed to uninstall Asp.Net 5 RC1. When I try to uninstall it, the msi installed borked while looking for AspNet5.ENU.RC1_Update1_KB3137909.exe.
